I have this exact amp. Hooked up to 2 10"kickers ,in sealed box no ports..I'm telling y'all non believers these amps are on another level. Definitely recommend not to much but no slug

Great editing! Good video keep it up!

Keep up the good work sir am also a repair guy too living in florida now am from Jamaica been doing repair for 19 years now so if any one need speaker amplifier equalizer you name it repair well am here

when you got a burn pcb try cleaning it with some alchool ( in romania we call it "izopropilic" ) it take the burn marks away, and after the soldering i clean the board again with alchool because it looks almost like brand new

When replacing the chopper mosfets with alternative types I would also take into consideration its / their on resistance not just the gate turn on voltage as the on resistance determines the current through the switching transformer and hence power rail voltages.

I have 3 old Rockford for you. Just saving up for the repairs

I've had one of these amps for almost 20 years. Still works excellent. 270 watts bridged at 4 ohm. Made In U.S.A. Old school power.

Seth Tips FTW!

Great vid bud. I'm doing research on doing paste on old amps to make sure they don't over heat. The amps work fine but have just been sitting in a garage for 20 years. I have 2 ppi a200 a friend is willing to give me for nothing so I would like to try and pull the boards and replace the thermal paste to insure they work for a while. Any thoughts on how long you think the factory paste lasts?

How does one identify which driver transitor to use? I've got two blown ones on my T3000.1 both with the code 2GM7 on them. But when I look up that code it gives me nothing. Also what's your thoughts on the 75344G mosfet that came in these? Thanks brotha, love your videos

Good job 👍🏻! Fix my amp

You see a ton of Amps! I need a Marine 4 Channel it going to be moved into the Bathroom because Priorities. Do you have anything you suggest that are thy best well built Amplifiers knowing im on water so Im not spending a ton. Was looking for enough RMS Power to Rock the Waterways in NY! Salt Water Loves to Kill all! Almost makes sense to get a disposable amp every other session!

Unusually satisfying to watch. Thanks man. At 25:15 is it me, or did you touch nothing, while calling out a read of "nothing,nothing,nothing"?

I have a RF 1000.4 amp, on turn on, (no signal, engine off) it sounds almost like alternator whine, as soon as i give it a signal, that noise completely goes away and then I hear the normal slight hiss. Any ideas what it could be? Im guessing there is some sort of muting circuit.

I’ve got a Rockford 4600 that blew an output FET. I pulled the two FETs and poking around I discovered that the main rail +caps are at 18V , probably about right as the caps are 25v rated. The - rail is at -27V. Any ideas where to look? Can’t find any bad components. I even replaced the TL494 and LM339M chips, no change.

I have a 2002 model 1500.1bd with two smoked fets,still plays but i wanna fix it before I really kill it

But yes your right I could do that so I don't have to fine a place for the ground clip. Just put the bridge plate to earth ground on my power supply....

Hello from Mexico my friend, I have a Rockford fosgate 800.2 power amplifier with almost the same failure as you show in this video, I reviewed the supply voltage for high (+50V, -50V) and also the regulator voltage in this case (+20, -20) they are OK, also I measured the signal from drivers and I got a similar signal like you, but when I install the MOSFET (original number) this works only for a minute and then MOSFETS goes to dead also power resistors (0.1 Ohm). Please let me know some recommendations to repair my power amp. Thank you very much in advance!

All amps can drive at that frequency, it's the fact that the sub itself can't audibly "play" that frequency, it'll just move...

Older class D with no negative feedback circuit sounded bad, but any decent modern class-d should be audibly transparent (up to about 10khz, then you get a bit of distortion, but any harmonics of 10k are at least 20 and thus inaudible).

The downfall to this bad ass amps are the power terminals! The wire guage size they made for way too small. They over heat the amp. Melt the plastic on terminals. I ruined two amps cuz of the terminals being too small to fit bigger guage wire

Well the MOSFETs used are OK for regular A/B class, but in this case may not be optimal for D-class car amp use. And of course people abuse them constantly. For some reason I was never a Rockford fan, and this amp is not special. I liked the old Phoenix Gold amps and a few other brands but that was some 30 years ago when nobody even though of a few kilowats D-class amps and clipped waveforms in audio files - a very kosher way of making music. When I heard Earl Zausmer BMW in 94, I was literally in car audio heaven, yes tube amps in the car.

Less talking and more working .
